Question 

fo = open("C:\Program Files\NPKI\yessign\User\SignCert.der","rb")
sssd = fo.read()
std = "SignCert.der"
cursor.execute("SELECT * FROM NPKIInf WHERE nSeqNum=5")

cursor.execute("insert into NPKIInf(nSeqNum, nFileName, nBinary) values ('7', '" + std + "', '" + sssd +"')")
cnxn.commit()

Above is the code and the error msg is down below:

C:\Python27>python import.py
Traceback (most recent call last):
  File "import.py", line 12, in <module>
    cursor.execute("insert into NPKIInf(nSeqNum,nFileName,nBinary) values('7', '" + std + "', '" + sssd +"')")

Connection to DB is Fine, I also tried just inserting hard data like

cursor.execute("insert into NPKIInf(nSeqNum,nFileName,nBinary) values('7','test','test'")

Still doesn't work.

this is the information of DB Table:

 CREATE TABLE [dbo].[NPKIInf](
           [nSeqNum] [smallint] NOT NULL,
           [nFileName] [nchar](50) NULL,
           [nBinary] [varbinary](max) NULL,
           [nHspName] [nchar](50) NULL,
CONSTRAINT [PK_NPKIInf] PRIMARY KEY CLUSTERED
(
           [nSeqNum] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF,
ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

What am I doing wrong? Thanks in advance.

Was it helpful?

Solution

it looks like you aren't converting to the correct datatypes, when I ran the following on SQL Server:

insert into NPKIInf(nSeqNum,nFileName,nBinary) values('8','test', 'test')

it failed, when I ran:

insert into NPKIInf(nSeqNum,nFileName,nBinary) values('8','test', cast('test' as varbinary))

as far as you're actual query goes, take a looke at: Inserting pyodbc.Binary data (BLOB) into SQL Server image column

and it should answer your question

OTHER TIPS

The error messages says your (single) quotation marks do not pair.

[42000] [Microsoft][ODBC SQL Server Driver][SQL Server]문자열 '0???뜝詵? *낷놑 '의 따옴표가 짝이 맞지 않습니다. (105) (SQLExecDirectW); [42000] [Microsoft][ODBC SQL Server Driver][SQL Server]'0???뜝詵? *낷놑 ' 근처의 구문이 잘못되었습니다. (102)

Your sssd must have at least one quotation mark in it, corrupting your directly built query sentence.
